C++ Example – Insertion Sort Algorithm






Insertion Sort

  • Idea: Start at position 1 and move each element to the left until it is in the correct place
  • At iteration i, the leftmost i elements are in sorted order.
  • Sorts list by moving each element to its proper place.
  • Efficient for sorting small numbers.
  • In place sort: Takes an array A[0..n-1] (sequence of n elements) and arranges them in place, so that it is sorted.
  • Attempts to improve high selection sort key comparisons.
